*The Masaru mentioned in the beginning is not Katsuki’s father
Masaru felt a pair of sturdy hands grabbing his shoulders, startling him out of his daze. Before panic set in, the young boy looked up and found himself relaxing upon noticing the familiar set of warm brown eyes and navy bellhop cap.
“Are you okay Masaru-san? You really should be mindful of your surroundings while walking home.” Genji-san, the apartment building doorman stated while nodding towards the new decorative columnar shrubs lining the doorway. Adorned atop the newly placed potted plants were ribbons, ornaments, and lights, likely new decorations to welcome the upcoming holiday season.
Masaru wrapped his father’s scarf tighter around his neck in hopes to mask his growing embarrassment. His pops had lectured him on multiple occasions to be more aware of his surroundings, a lesson that seemed to fly over his head each time. Well, it wasn’t so much a lecture as it was just him grumbling “stop being a fucking dumbass like your dad” while slapping a bandage onto his injury for the week, but admittedly, his main point was clear. “I’m sorry sir” he bowed “I’ll try to be more careful.”
Genji-san simply laughed as he started to lead the way into the apartment lobby, Masaru following suit. “In the eight years you folks have lived here I have never seen you be careful.” the doorman stated with jest, like he was sharing a joke with some old friends.
Masaru bid the doorman farewell as he swiped his key fob, pressing the elevator button for floor 12. As the elevator continued its ascent, Masaru felt the events of today weighing more heavily on him. It’s not as if he had never received a letter from an admirer. Although he didn’t stand out as much as his sister, by default, having two famous pro heroes as parents meant Masaru naturally attracted a lot of attention (and trouble) whenever he went. That being said, getting a note with such particular phrasing was unusual in his experience.
Just as Masaru started to type the apartment pin into the door keypad, the front door swung open to reveal his dad adorned in an All Might Christmas sweater, a light up reindeer headband, gym shorts, and matching All Might holiday socks.
“Masaru!” Izuku exclaimed as he excitedly scooped his son into a big hug before shuffling him back into the apartment.
“O-oh, hey dad” Masaru stammered out as he tried to balance hugging his father back and not tripping while taking off his shoes in the genkan. “I didn’t realize you had already finished patrol for the day.”
“Oh! Well, yes I was supposed to be out later, but my hero suit has some mechanical issues so I was discharged for the day.” Izuku explained as he walked down the hallway towards the kitchen. “Are you hungry? We still have some of your pop’s kare raisu from last night.”
“Um, sure, I could eat a bit.” Masaru replied, planting himself on one of the kitchen barstools as he swung his backpack off his shoulders. Izuku placed a sizable helping of the curry dish onto a plate, sliding it into the open overhead microwave. After putting some food items away, he turned to face his son. As if in deep thought, the green haired man tilted his head. “Is something bothering you?”
“Huh?” The young boy looked up, perplexed.
Izuku paused briefly to grab the now heated dish and slid the plate of food over with a glass of water before settling himself down in a barstool across from his son. He waited patiently, leaning on his forearm as he stared at the other.
Masaru looked down at the food, pushing a piece of carrot back and forth as he thought about whether or not he wanted to share what happened at school today. “How could you tell?” He asked in reply, both out of actual curiosity and in an attempt to deflect.
Izuku simply smiled “You are my son, you mumble when you’re in deep thought.” Masaru huffed in annoyance, remembering all the times he would complain about his dad’s constant muttering being a pain when asking for help on his math homework. After chewing on a piece of spiced chicken for longer than necessary, Masaru finally decided to reach into his backpack and pull out a small red envelope. He supposed this was something worth being honest about.
“I got a letter from a…friend.” The boy explained, though calling the sender a friend might have been too generous. Frankly up until this point, Masaru wasn’t even sure if Daiki could even tolerate his presence. “He wants to go out on a date?” he explained as he slid the envelope across the kitchen counter.
Izuku picked up the envelope, slid the letter out and unfolded the card to read the enclosed message “Go out with me, or else.” he read aloud.
“I got this letter from a classmate named Daiki in my class. You might have seen him? He’s the student with the metal manipulation quirk who won second at the sports festival. He’s…kind of weird? He just sort of decided I was going to be a rival of his since I’m also in the hero course and I have two pro heroes as parents, but I’m not even that strong…I don’t really get it…anyway point is, he left this card in my locker and I’m…concerned.” Masaru rambled in an attempt to explain the relevant circumstances that led up to this point.
“Hmm…yeah I remember him. A really interesting quirk. His control over metal gave him a huge advantage over students with intricate costumes at the licensing exam…So do you want to go out with him?”
“H-huh!?”
“Well he’s asking you out right? Do you want to go out with him?” Izuku asked.
“Who asked out our kid?” Katsuki asked, entering the kitchen space with groceries in tow. He leaned over, expecting a kiss from his partner, only to get smacked in the face with Daiki’s note. Katsuki leaned back, grumbling at his lack of kisses while he quickly skimmed the brief message. “Hmm, so do you want to date this punk?” He asked, turning to sort a bag of vegetables into the fridge while he waited for a response.
“I-I mean…aren’t you guys…” Masaru started, waving his hands as if to emphasize the peculiarities of his circumstances.
His dads both slowly stopped what they were doing, turning and waiting expectantly for their son to explain himself and his hesitance.
“I j-just mean…” Masaru swallowed, trying to properly vocalize his confusion “Aren’t either of you concerned that this, er, ‘request’ for a date is basically a threat?”
“A threat?” Izuku asked out loud, clearly confused as he instinctively looked to his lifelong partner for clarity. Katsuki didn’t say anything, but it seemed like he successfully communicated with merely a look that he wasn’t sure what his kid was referring to either. “I mean, your father basically asked me out on Valentines Day the same way…so I wouldn’t really say it was a threat.” Izuku replied.
Masaru felt his universe tilt on its axis ever more slightly than he could handle. “Pops did what.”
“We never told you? I could have sworn-- wait one second.” Izuku stood up and walked over to the cabinets under the TV in the adjacent living room. After some rustling and a suspicious bang (to which Katsuki swore that if Izuku broke another appliance with his super strength there would be hell to pay), his dad returned to the kitchen counter with a worn out chocolate box and corresponding envelope.
Masaru flipped open the envelope to find a card. The card was surprisingly well maintained for how aged the outside envelope seemed. The front of the card held a decorative floral design with the words “Wishing you peace and comfort.” Flipping the card open, Masaru found the standard printed message of “I’m so sorry for your loss” along with a handwritten message at the bottom that said “I’m the best you’ll ever find, go out with me.”
Masaru closed the card ever so slowly, like he was concerned any sudden movements would lead to a bomb going off, as he turned to face his dad with a face he imagined was full of confusion and concern.
“Dad?”
“Yes Masaru?”
“You said you got this from pops on valentines day…? I’m assuming as a valentine?”
“Yes, firecracker.”
“Why did pops give you a condolences card for Valentines Day!?” Masaru sputtered in indignation as each of his concerns were slowly confirmed.
“Because its a shame he went that long in his life not dating me.” Katsuki added nonchalantly as he moved a bowl full of dough mixed with scallions to the kitchen island where the other two were still sitting. Probably to make scallion pancakes as a side dish.
Izuku sighed, looking at his partner like he was falling in love all over again. “Your father has always strived to be the best. It’s what I admired about him, the very symbol of victory. His confession was basically to show me that my life would be much better with him in it because he is the best that there
is.” His dad explained, like as if this statement was as clear as day.
“So...is this how pops has always flirted with you...?” Masaru asked carefully. Part of him wasn’t sure if he wanted to hear the answer to this question. He felt like he was sailing in unchartered waters, at risk of being stranded at sea.
“Mhm!” Izuku nodded excitedly “I’m definitely a lucky guy!”
“...So neither of you are concerned that a classmate from school left me a note that demands I do something ‘or else’???” Masaru clarified again, making sure he fully understood where his parents stood.
Katsuki merely shrugged at the question, more preoccupied with kneading the dough before rolling it out. “Kid is confident and knows what he wants, and he better have a backbone if he wants to ask out my son.”
Masaru looked back and forth between his parents, contemplating the possible brain damage the two experienced that led them to normalize such mannerisms as romantic behavior. In the end, he decided that his parents may be some of the most famous pro heroes to exist on this planet, but they were also a bunch of fucking whackos. Grabbing his bookbag, Masaru quickly excused himself to get started on his homework, making a beeline for his bedroom away from his parents.

“Why are you looking up ‘tips on how to communicate with emotionally awkward parents’?’” Yoko questioned as she levitated her brother’s computer to her for a closer look.
Masaru rolled his head over so he could look at his older sister with his head still down as he explained his current situation. How he is somewhat concerned about the letter he received because of the wording, but also how his parents don’t seem to be able to interpret a potentially threatening letter from a love interest as anything but romantic.
Once Masaru finished explaining, Yoko simultaneously used her telekinesis to place her brother’s laptop back on the desk as she pulled his pillow into her hands. “Give me 10 minutes, and I can fix this no problem.” she proclaimed easily as she left the doorway to walk down the hall towards the living room.
Masaru sat there in silence, wondering what his sister was up to, before he heard his dad yelp in surprise and his pops shout in anger.
“The hell, stop ppfft-- stop hitting me with a pillow!”
“Yoko sweetheart! What are you-- Ow!”
“For your information, most people don’t flirt by threatening each other! Which means *thwack* If your son is *thwack* worried *thwack* about a threatening message by a classmate *thwack* you need to take his concerns more *thwack* seriously! Honestly! You would think as two pro heroes you both could properly recognize a threat *thwack* oops, sorry Dad, didn’t mean to knock your glasses into your soup.”
Masaru tentatively poked his head out from his bedroom doorway, peaking just around its edges to find both his fathers on their knees in shame as his sister proceeded to lecture the living daylights out of them. Yoko was like their dad in that she could talk at the speed of light, but she had their pop’s vocal chords. This meant that when she was upset, Yoko could take on their pro hero dads heads on with no issue. Masaru always thought his sister would have made an excellent pro hero if she wanted to because of the way she carried herself. However, Yoko really wanted to build a career for herself as a structural designer outside of their parents’ legacy, something their pops was very proud of.
“Now” Yoko’s sudden change in tone snapped Masaru out of his thoughts “be supportive parents and ask Masaru how the note made him feel before you decide how he should feel from it.” She commanded as she handed Izuku a tissue for his soup covered glasses.
“Yes of course, we’re sorry Masaru, we should have asked you first how the situation made you feel.” Izuku apologized, smacking Katsuki who
was still sulking at being scolded like a child. All Izuku could get from the blonde was get a begrudging huff of indignation.
“Well…I wasn’t super concerned that Daiki was actually threatening me. I mean we’re both in the hero course and I think in terms of integrity we should all know better? But…” Masaru paused, feeling oddly uncomfortable at the idea of this conversation becoming heavier in a sense. He looked to his dad, who nodded in support, urging him to continue explaining.
“I guess I just don’t entirely understand where his feelings are coming from?” Masaru continued. “He doesn’t even seem to like me that much so this whole confession caught me off guard? I mean the amount of times he has just randomly gone out of his way to kick me and yell at me about how I’ll
never be a better hero than him doesn’t help, but-- Pops, where are you going?”
“I’m about to teach that brat a lesson for bullying my son.” Katsuki stated as he threw a jacket on, already out the front door.
“Kacchan! We just said we were going to listen to our son!” Izuku exclaimed, running after his partner out the front door. The two siblings stood there, unsure of what to do now that it seemed like one of their fathers was on their way to commit a potential crime. They could hear their dad shout “You don’t even know where this kid lives!” as they heard the stairway door slam shut.
“You think I should let the police know GEMG Dynamight is on the way to potentially beat Daiki up?” Masaru thought out loud, not really expecting an answer to his question.
“I think we need new dads.” Yoko replied, throwing Masaru his pillow back as she made her way back to her bedroom, calling it a night.

Somehow, three generation of Bakugos ended up at the local police office. After going on a rampage across the city, Masaru’s parents were both arrested and brought in for further questioning. In need of an adult, Masaru reached out to his grandparents so that they could accompany him to the station. (Yoko legally was an adult, but she decided this wasn’t going to be her problem tonight and locked herself in her bedroom)
Though, Masaru didn’t think his sister was necessarily wrong by the looks of how Bakugo Mistuki was currently ripping her son a new one.
“If you used the brain I spent so long growing in my god damn womb! You would have realized that attacking a minor! In the middle of the night! Would *SMACK* land you in loads of trouble! *SMACK* with the law! HOW ARE YOU EVEN A PRO HERO.”
“STOP HITTING ME HA--”
“I’LL HIT YOU AS MUCH AS I WANT BRAT!”
“H-honey please…! We don’t want to get the boys in more trouble with the law!” Masaru senior stuttered, attempting to calm the two explosive blondes.
…Maybe I just need a new family in general. Masaru thought to himself as he watched the scene unfold.
After some profuse apologizing from both him and his grandfather, the police, in respect of Heroes Deku and Dynamight and their service to the nation, decided to let them off with a warning. His grandparents proceeded to drive the three of them back to their apartment in near silence. Mitsuki proceeded to escort his parents to the front of the building, pausing under the entrance to give a more tempered lecture to the two. Masaru and Masaru senior waited in the car, deciding to give the three some space (and to put some distance between themselves and two of the most volatile
personalities they knew).
“They mean well.” Masaru senior began.
Masaru junior hummed, sliding further down into his seat as he thought about his night “I know they mean well…I just think they have had to overcome a lot of adversity to love each other the way they do now, so they see expressions of affections very differently.” The two watched as Izuku started to rub the back of his neck in a embarrassed fashion, bashful of their behavior as parents today as Mitsuki continued to talk. Katsuki started to avoid eye contact with his mother, shoving his hands into his pants pockets like a child that got caught stealing cookies from the top shelf.
“But no matter what, I think I’m in good hands.” Masaru spoke softly, mostly to himself like a hushed prayer, as he looked out the car window.
His grandfather smiled and nodded, following his gaze as they watched their rambunctious family flourish.
